Multi-material joining of aluminium to steel is mainly restricted due to their different thermo-physical properties, melting temperatures, low solubility and in particular, formation of brittle intermetallic phase layer at the joint interface. Various joining processes have been attempted to join aluminium and steel sheets with an aim to reduce the growth of phase layer by precise control of heat input. However, laser beam and arc based joining processes are popular among other joining processes due to their strict control of heat input with regulative metal transfer and flexibility to join intricate shapes. A critical survey in joining aluminium to steel sheets by laser beam and arc based joining processes are presented in the present work. The influence of various joining parameters such as heat input, filler wire types on the growth of intermetallic phase layer thickness and corresponding joint strength are analysed and reported subsequently.

“…During penetration welding, the interactions of different substances in the welding zone under high temperature include not only chemical changes but also substance migration and distribution among different phases. Burning of metallic elements and the interaction between AF in the high-temperature molten pool and liquid metallic substances can change the properties of the welding joint [23,24]. To study the effects of AF on the welding joint, the distribution and diffusion of several specific elements (Fe, Cr, Zn, and O) at the welding joints of the test pieces with and without AF were examined through linear scanning analysis.…”

To study the feasvhibility of activating welding technique in increasing the width of low-power pulsed laser penetration weld joint and to improve the efficiency of lowpower laser welding while reducing cost, theoretical analysis and experimental verification are conducted in this study to determine the effects of activating flux Cr 2 O 3 on the welding performance of DC56D galvanized steel plate for a vehicle body. Research data on the variation in weld width, joint microstructure, mechanical properties, distribution of elements, and corrosion resistance are acquired. Results indicate that activating flux can effectively increase the YAG laser energy absorption of the steel plate and melting of parent metals, thus increasing the weld width. Although the joint microstructure is dominated by refined isometric crystals and columnar crystals, the heat-affected zone expands slightly because of the activating flux. No evident diffusion and segregation of active elements are observed in the weld joint. The involvement of activating flux does not change the relative contents and distribution of chemical components of the weld. The welded test piece with activating flux is superior to that without activating flux in terms of tensile strength, microhardness, and corrosion resistance, indicating that the addition of activating flux effectively improves the performance of low-power laser penetration welding test pieces.

“…The reported literatures suggest that the joint quality can be improved significantly by controlling the heat input [3][4][5] . Various methods such as laser beam and laser-arc hybrid joining 2,[6][7][8][9][10][11][12][13][14] , arc based joining [3][4][5][15][16][17][18][19][20][21][22][23] and friction stir welding [24][25][26] are employed to join aluminium and steel sheets with an aim to control the heat input during joining of such dissimilar material combinations.…”

A coupled experimental and theoretical investigation on joining of aluminium and galvanized sheets in lap joint geometry using an advanced pulsed current gas metal arc based process is presented. The experimental study was focussed on finding suitable processing conditions to restrict the heat input, and minimize the growth of the phase layer thickness and the formation of Fe-Al intermetallic compounds along the joint interface. The theoretical study included the development of a three-dimensional heat conduction model to compute the temperature field and thermal cycles, and estimate the final joint bead profiles and phase layer thickness as a function of processing conditions. The estimated results are tested extensively for a wide range of experimental conditions. The experimentally measured and the corresponding computed results show that the dissimilar material combinations of aluminium and galvanized steel can be joined successfully by pulsed current gas metal arc with a precise control of processing conditions and heat input.
